Primitive Jawed Fish Fossils Suggest Jaws And Teeth Evolved Simultaneously

Tags: , , ,

OTTAWA, ONTARIO – New research led by University of Bristol’s Dr. Martin Ruecklin proves the oldest jawed vertebrates had teeth, which suggests teeth and jaws evolved together.

The paper Development of teeth and jaws in the earliest jawed vertebrates was published Oct. 17 in Nature, the International Weekly Journal of Science. The study is telling, as previous research suggested the first jawed vertebrates were toothless.

Dr. David Bartos, a beauty dentist in Ottawa, and his partner Dr. Mark Northcott are interested in how this research shows the tightly linked harmony of our teeth and jawbones. Our six family dental offices serve patients in the greater Ottawa area, and we help improve jaw function and placement with neuromuscular dentistry.

The team included researchers from across the globe. Swiss physicists joined forces with paleontologists from the University of Bristol, the Natural History Museum and Australia’s Curtin University to study the prehistoric jawed fish Compagopiscis. The team used well-preserved fossils and high energy X-rays to learn how the fish’s teeth and jaws developed.

“We were able to visualize every tissue, cell and growth line within the bony jaws, allowing us to study the development of the jaws and teeth,” says Dr. Ruecklin. “We could then make comparisons with the embryology of living vertebrates, thus demonstrating that placoderms possessed teeth.”

The high energy X-rays are not invasive. This method gave the researchers extremely detailed data without destroying the fossil. Scientists previously thought these ancient vertebrate species were toothless and used their jawbones like scissors. The study gives firm evidence that primitive jawed vertebrates had jaws and teeth.

“These wonderfully preserved fossils from Australia yield many secrets of our evolutionary ancestry but research has been held back waiting for the kind of non-destructive technology that we used in this study,” says Natural History Museum researcher Dr. Zerina Johanson. “Without the collaborations between paleontologists and physicists, our evolutionary history would remain hidden in the rocks.”

Drs. Bartos and Northcott practice neuromuscular dentistry, a treatment philosophy which finds the delicate balance between your facial muscles, your temporomandibular joint (TMJ) and your bite. We understand the complex relationship between your teeth and jaw, and our custom orthotics will help you stabilize your bite. You may suffer from migraines, neck and face pain, ringing ears, a popping jaw or numbed fingertips. All of these symptoms may stem from your misaligned TMJ. Contact our team to test your jaw alignment with our advanced technology. We also offer
orleans dental implants, teeth bleaching and Invisalign treatment.

Treating TMJ Disorders With Neuromuscular Dentistry

Tags: , ,

Ottawa Neuromuscular Dentistry and TMJ DisordersOTTAWA, ONTARIO – Ottawa  family dentistry keeps teeth and gums healthy for life, but let’s remember that teeth aren’t the only factor affecting your bite.

General and cosmetic dentists focus mainly on the teeth, the gums, and sometimes the bones. Neuromuscular dentistry focuses on aligning the jaw into its ideal place, and to do so, dentists must manipulate not only teeth, but muscles, tissues, nerves, and the temporomandibular joint (TMJ).

TMJ Disorders
The TMJ connects the lower jawbone to the skull. Humans have two TMJs, one on each side of the face. Sometimes TMJ disorders are incorrectly called TMJ; the correct term would be TMD, for temporomandibular joint disorder.

Occlusion is the term for how your upper and lower teeth come together. If the teeth and jaws are out of line, we call this malocclusion – bad bite. Malocclusion can cause patients to develop TMJ disorders. If the jaw muscles are being overworked, they can start to spasm.

 

Signs and Symptoms

People experiencing pain or locking in their jaws may suspect a TMJ disorder, but some symptoms can be even more subtle. Some patients develop pain in their backs and necks. Other symptoms include facial swelling, numb fingertips, recurring ringing of the ears, dizziness and tender teeth. If your jaw clicks when you open and close it, this could be a sign of TMJ syndrome. In some patients, the pain associated with TMD can be misidentified as an earache, as the TMJ is so close to the ear. Serious headaches can cause patients pain, when the real problem is in the joint of their jaws.

Neuromuscular Dentistry
Dr. David Bartos and Dr. Mark Northcott focus on the niche field of neuromuscular dentistry. In their Ontario offices, the dentists can significantly change your bite, moving your jaw to its prime position. To accurately evaluate your mouth, we will first need to see your muscles and bones in an inactive position. Using the transcutaneous electrical nerve stimulator (TENS), we relax the muscles in your face and jaw. Once your jaw is completely rested, we use the Myotronics K7 system to take detailed dimensions of your mouth and jaw, allowing us to capture the perfect measurements to treat your TMJ disorder. After we’ve successfully measured the movement of your mouth and jaw, we’ll create a custom mouthpiece – or orthotic – just for you. This mouthpiece will gradually move your jaw to the correct position. After the orthotic has improved your bite, there are usually other options available, including orthodontics and recontouring of the teeth.

Drs. Bartos and Northcott are passionate about their work in neuromuscular dentistry.

“Being able to practice this type of dentistry is professionally very satisfying because we can change a person’s life,” says Dr. Bartos. We can take a chronic pain patient who suffers from debilitating headaches or neck and back pain, or one of the other symptoms associated with TMD, and return them to a normal way of life. That’s a real privilege.”

The process of eliminating pain and TMJ disorders isn’t a quick one. Once the orthotic has gently moved your bite to its ideal placement, we can then implement restoration dentistry to further improve your bite. By slightly altering your bite with the use of bonding, crowns or implants, we can put the finishing touches on your occlusion, thereby eradicating your TMJ-related pain. Patients need not suffer from TMJ problems, as neuromuscular dentistry is effective in solving these painful issues.

The Trillium Dental team also offers in-office teeth whitening, dental implants, root canal treatments, routine cleanings, and general, restorative, and cosmetic dentistry procedures. If you’re apprehensive about our procedures or suffer from severe dental phobia, we offer the option of IV sedation for your visit.

What Is Neuromuscular Dentistry?

Tags: , ,

Filed under: Neuromuscular Dentistry — Tags: , , — David Bartos @ 7:15 am

Ottawa neuromuscular dentistryIf you’ve ever heard a dentist or another medical professional use the term neuromuscular dentistry, you may have wondered what exactly neuromuscular dentistry is.

Essentially, neuromuscular dentistry is concerned with treating problems like bruxism and TMJ-dysfunction. In both cases, patients may experience painful symptoms like frequent headaches, neck and facial pain, popping or cracking of the jaw, ringing ears, or numbness in the fingertips.

At Trillium Dental, our doctors can provide effective relief for painful symptoms through neuromuscular dentistry.

Treatment starts with identifying the patient’s ideal alignment. We do this by relaxing facial muscles with our TENS (transcutaneous electrical nerve stimulator) unit, an experience which many patients enjoy as it also relieve painful symptoms. Once we’ve determined your ideal alignment, we can begin taking measurements for your custom made orthotic. An orthotic is a special mouthpiece that is made by our lab and corrects alignment, bringing long-term relief to symptoms.

Do you have trouble with either bruxism or TMJ-dysfunction? Don’t put off treatment any longer. Call one of our Trillium Dental offices today to schedule a consultation appointment. We serve patients for cosmetic dentistry and iv sedation from Ottawa, Nepean, Kanata, Stittsville, and Orleans.

You don’t have to live with painful symptoms any longer!
